NHK Wildlife - Guardians of the Kelp Forest: Sea Otters (2012)

Posted By: Tutorial

Date: 6 Jun 2016 10:16:55

Monterey Bay has a dense underwater forest of giant kelp - the largest on Earth. This forest of 60-meter long kelp provides an ideal habitat for sea otters. This program follows a family of sea otters living in close harmony with this environment, revealing not only how sea otters thrive amongst the kelp but how they also help protect the kelp in turn. The mother spends all of her time and energy raising her newborn. Her young pup learns how to crack open shellfish by imitating her. She desperately tries to protect her young from a seagull attack. These are just some of the amazing moments captured in this rare and intimate animal family portrait.
